​The Inspiration

Although thousands of Luftwaffe pilots fell in love with the 109, Willy Messerschmitt wasn't appreciated by everyone in the aircraft industry.  In particular, he had run afoul with Erhard Milch in the 1930's.  As the head of the Reich Aviation Ministry, Milch refused to honor Messerchmitt with the "Me" description for the 109.  Instead, he insisted that the aircraft be named Bf 109 after the Bayerische Flugzeugwerke plant where it was produced.  Bf 109 was the official designation in  German government documentation of the time.  Of course, the Allies and even Luftwaffe field units were free to diregard this directive.

Bf 109 Variants

Oddly, the very first 109 to take to the air  was powered by a  Rolls Royce Kestrel engine.  Because this engine was "upright", V1 had a very different appearance than her progeny.

From V2 onward, the 700hp Junkers Jumo 210 inverted vee powered all Bf 109 models until the Emil arrived with its 1100hp Daimler-Benz DB 601.  The Jumo-powered birds are identified by their large chin scoop, single small underwing oil cooler, and small carburetor scoop.  Several changes were made to the exhaust stacks, ranging from rows of mere holes in the cowling to individual pipes nearly

Many modelers gravitate toward the battle-hardened Gustav and later models, but my preference is for the cleaner lines of the early 109’s from V2 through the Emil.  For this reason, this plan focuses on the Jumo-powered versions but details are included in the plans for upgrading to the Emil variant. The addition of the boxy underwing and chin scoops, a supercharger scoop, and the late-style exhaust stacks are all it takes to turn this model into an E. 

The Model

After a string of 30" fighters, the time had come to move on to bigger things. An easy way to step into this was to simply scale up one of the 30" designs by 150%.  Retracts were added, and that prompted an improved wing design. The 30" version is a great parkflyer, but the bigger bird is at least 150% more fun.

Well worn Doras went to training squadrons.

Here is a Dora and an Emil showing how a simple swap of the scoops can change the variant.
